We are seeing a confluence of things this season, and the root of it goes back to last year. If you watched the offense against certain teams, you saw the problems especially with the WRs winning their match-ups. The thing is, most teams and coaches are stubborn and think they can do it "their way". It took time, but now more teams are willing to play the game a certain way when playing against the Packers. The blueprint is there and teams are less stubborn and all are employing a certain set of defensive tactics.
- You can't play a lot of zone against the Pack or AR will find guys. You have to play man.
- If you play man, you can't let AR out of the pocket. Therefore, control your pass rush and don't let him get outside. Contain him like you would R. Wilson. The bonus is that the line is susceptible to bull rushes. You don't need to try and fool them with upfield speed rushes. Just take them on man-to-man and the pocket will collapse with some regularity.
- Bring an extra man on the pass rush a fair amount of the time. You don't need to worry much about getting burned in the underneath middle, the Packers don't have a TE that can hurt you and he can easily be covered by a LB. They also don't use the RBs very much. (Again, the bonus is that the blitz will keep the RB from getting in the mix as a receiver.)
- You don't really need to keep 2 safeties deep, and this year you probably don't even "need" 1. They just aren't going to beat you deep very often. Take your chances and cover the mid-level areas to prevent crossing routes. The bonus again is that it helps stop what is already a somewhat anemic run game.
These things have been building for awhile, but when you had Jordy, you made them pay for playing man and not having 2 deep safeties. If they did double Jordy, Cobb had more room. If you dropped both your safeties deep then Lacy would give you trouble, or Cobb again had more room on the mid-level underneath type crossing routes. None of those things are options this year.
This won't be fixed until you deal with the personnel issues (though some scheme changes could make things better).
1) You need a stud WR - it's likely Jordy comes back and is that guy. If in doubt, draft one high.
2) You need a stud RB - can you get Lacy to stop eating and get him to spend the last week of June and the first 3 weeks of July getting in prime shape and getting down to 240#. If not, you need to draft a RB. (fortunately, good ones are often available in non-premium rounds)
3) You need a TE with some ability to run away from LBs thus forcing a safety into coverage - Rodgers is not that guy. Not sure if Perillo or Backman can be, but I'm thinking you need to draft one.
4) Lastly, your OL is not good. You need to draft one high and add depth in a later round so that you don't have to play one-legged guys because the back-ups are sorely lacking.
